[0011] In view of the prior art, the object of the present invention is to contribute to the prior art and to provide a device suitable for improving at least one of the above-mentioned aspects of the prior art, respectively. In particular, the object of the present invention is to provide a damping member having a better balance between functionality and cost-effectiveness and enabling efficient valve-related modifications. Summary of the invention

[0012] The object is solved by the features of the independent claims. The dependent claims have further embodiments of the disclosure as their subject matter.

[0013] According to one aspect of the present disclosure, a damping member for a pneumatic valve of a pneumatic system of a vehicle (particularly a multi-purpose vehicle) is provided, wherein the valve includes an air outlet section for discharging pressurized air; wherein the damping member is suitable for being mounted to the air outlet section for damping acoustic emissions of the pressurized air; the damping member includes a support structure; and the support structure is suitable for conducting air through the support structure to damp the acoustic emissions of the pressurized air.

[0014] The damping member is adapted to be mounted to the air outlet section. Thus, compressed air can flow from the air outlet section into and / or through the damping member. Wherein, acoustic emissions of the pressurized air are suppressed by conducting the air through the damping member.

[0015] In order to achieve damping, the damping member includes a support structure. According to an embodiment, the term "support structure" may refer to a plurality of repetitive features in a single-piece part, which have the property of attenuating noise / vibrations at the air outlet section. In particular, a plurality of repetitive features are distributed in the single-piece part in a manner equidistant from each other. These noises and / or vibrations are caused by the pressurized air leaving the air outlet section. It is also conceivable that the support structure may be a single-piece part consisting of a plurality of elements attached together and / or consolidated to form the support structure. The support structure is suitable for enabling the air flowing through the support structure to be deflected, distributed and / or diffused to the nearby atmosphere. This achieves damping, i.e. suppressing acoustic emissions such as noise and / or suppressing vibrations.

[0016] It should be appreciated that such a support structure may be an alternative to a combination of a grid and a cover for exhausting the solution. A cover for supporting the support structure and / or the damping member may be omitted. This may improve cost effectiveness and / or manufacturing processes.

[0017] Furthermore, the support structure can fulfill multiple functions and can construct the damping member according to different desired and / or required constraints related to, for example, geometry and / or damping capacity. The support structure and therefore the damping member can be effectively adapted to the specific design and / or geometry of the valve and its internal geometry. That is, the support structure can effectively customize the damping member.

[0018] Optionally, the support structure is a repeating structure. That is, the support structure includes repeating parts with similar and / or equal geometric and / or mechanical properties. Additionally or alternatively, the support structure is a layered structure. That is, the support structure can be composed of multiple geometrically and / or mechanically equal, similar and / or different layers. The support structure can include translational symmetry. The repeating structure and / or layered structure enable the support structure to include a modular geometry, wherein the layers and / or repeating parts can be modules for guiding air, and wherein each module can include dedicated functions, such as for suppressing acoustic emissions and / or guiding air. The repeating structure and / or layered structure can therefore also realize support structures of different sizes, because the support structure includes multiple layers and / or repeating parts.

[0019] Optionally, the support structure includes a plurality of holes for damping acoustic emissions of air conducted through the damping member. The holes (e.g., cavities) can effectively guide and distribute, deflect and / or diffuse air within the support structure to achieve damping of acoustic emissions. The holes can include the same and / or different typical sizes.

[0020] Optionally, the damping member is made by an additive manufacturing process. The damping member can be efficiently designed and manufactured without any process limitations known from standard injection and demoulding. The damping member can be formed into a form that cannot be achieved by other methods (e.g., injection molding). The additive manufacturing process can improve the manufacturing accuracy of the support structure and / or can achieve smaller holes, layers and / or repeating parts than injection molding and / or by providing a grid. The additive manufacturing process can provide a variety of possible shapes and damping characteristics. In addition, the functional part, the mounting part and / or the functional guide member can be formed integrally with the damping member.

[0021] Optionally, the support structure comprises a functional guiding member adapted to guide air through the damping member, and the functional guiding member is adapted to deflect a main air flow of air and / or to divide the air into a plurality of sub-flows. That is, the support structure enables the damping member to comprise a different form to the functional guiding member in different areas of the support structure, which may not be possible using conventional manufacturing techniques. The functional guiding member may be used to influence the main flow direction of air within the damping member and / or to divide the flow into a plurality of sub-flows for enhancing damping and / or for further guiding the sub-flows through the damping member.

[0022] Optionally, the damping member defines a flow direction of air conducted through the damping member; and the functional guiding member is adapted to reverse at least one component of the flow direction while the air is conducted through the damping member, and / or the functional guiding member comprises a labyrinth, a meandering and / or a wavy shape. It will be appreciated that reversing the component of the flow direction can further enhance the ability of the damping member to reduce acoustic emissions. To this end, the functional guiding member comprises a shape that enables the reversal of the component of the flow direction. For example, the functional guiding member comprises a labyrinth, a meandering and / or a wavy shape.

[0023] Optionally, the damping member is made of a polymer, in particular a thermoplastic and / or thermosetting polymer, a metal and / or a composite material. These materials enable efficient manufacture of the damping member, in particular the support structure. In addition, these materials can achieve the mechanical properties required for the support structure. However, other materials are also possible, such as hard resins, soft resins, bioprinting materials. Composite materials can be used to manufacture damping members with different parts of a specific material, depending on their function. For example, the support structure can be made of a thermoplastic material, while the cover and / or cap can be made of metal. Thermosetting polymers (also called resins, such as hard plastics) enable the damping member and / or the support structure to be manufactured by stereolithography or other types of manufacturing techniques (in particular additive manufacturing techniques), which consist of hardened liquid materials.

[0024] Optionally, the damping member includes a mounting portion for fixing the damping member directly to the valve body of the valve. The mounting portion (i.e., mounting feature) may include a clamping member, an eyelet suitable for use with a fastening device, and / or any other type of connection. The mounting portion may achieve an improvement in the efficiency of assembly of the valve, and in particular an improvement in the efficiency of attaching the damping member to the valve.

[0025] Optionally, the damping member includes one or more functional parts to prevent water intrusion, for generating a pressure gradient, for self-cleaning, and / or for providing a mounting portion for the sensor. The functional part can guide air to generate a pressure difference, for example, one of the functional parts can generate a low pressure section to cause suction and / or self-cleaning characteristics. Additionally or alternatively, the functional part can protect the inner part of the support structure from environmental influences, such as the intrusion of water, other fluids and / or dust. For example, an integrally formed cover and / or an integrally formed component arranged in the outlet area as a protective member to prevent water intrusion can be provided. Additionally or alternatively, the damping member includes one or more functional parts for providing a mounting portion for the pressure sensor. The functional part can be suitable for mounting the sensor into the support structure and / or the damping member. The mounting portion can be arranged so that the sensor can measure the air flow through the support structure and / or the damping member and / or the exhaust air.

[0026] According to one aspect of the present disclosure, a pneumatic system of a vehicle, in particular a multi-purpose vehicle, is provided, wherein the pneumatic system comprises a valve having an air outlet section for discharging pressurized air and a damping member as described above, wherein the damping member is mounted to the air outlet section for suppressing the acoustic emission of the pressurized air by guiding the air through the damping member. Optionally, the damping member comprises one or more of the above optional and / or preferred features to achieve the corresponding technical effects.

[0027] Optionally, the pneumatic system is a pneumatic suspension system and / or a pneumatic brake system. It is recognized that in such a pneumatic suspension system and / or such a pneumatic brake system, the air may comprise a particularly large pressure. Therefore, the acoustic emission, which may depend on the damping element, is particularly important for such a system.

[0028] According to one aspect of the present disclosure, a vehicle, in particular a multi-purpose vehicle, is provided, which includes the damping component as described above and / or the pneumatic system as described above.

Optionally, the method is performed so that the damping component includes one or more of the above optional and / or preferred features to achieve the corresponding technical effects.

[0030] The method is particularly suitable for serial production of damping components, wherein a model is obtained once and a plurality of damping components can be manufactured by additive manufacturing based on the model.

[0031] Optionally, the model depends on the geometry of the valve, the air outlet section and / or the valve body. Therein, it is recognized that the damping member (i.e. its geometry and / or shape) is affected by the geometry of the valve, in particular by the geometry of the air outlet section and / or the valve body. Therefore, a model can be created such that the valve, the air outlet section and / or the valve body are appropriately taken into account.

DETAILED DESCRIPTION

[0041] Figure 1 A vehicle 200a, in particular a multi-purpose vehicle 200b, according to an embodiment of the present disclosure is schematically shown. In the following, the vehicle 200a, in particular the multi-purpose vehicle 200b, is referred to as the vehicle 200a, 200b. The vehicle 200a, 200b is a land vehicle 200a, 200b, such as a truck, a trailer, a vehicle train, a bus and / or a passenger car.

[0042] The vehicles 200a, 200b include a pneumatic system 201. The pneumatic system 201 is or includes a pneumatic suspension system 201a and / or a pneumatic brake system 201b.

[0043] The pneumatic suspension system 201a is adapted to support the vehicle 200a, 200b on the ground. The pneumatic suspension system 201a may include pneumatically actuatable components. Therein, pressurized air 200 is provided and controlled to actuate the pneumatic suspension system 201a.

[0044] The pneumatic brake system 201b is adapted to brake the vehicle 200a, 200b, i.e., a braking request by the driver of the vehicle 200a, 200b and / or an autonomous driving function may result in pneumatic and / or electro-pneumatic actuation of the pneumatic brake system 201b to trigger application of a braking torque, wherein pressurized air 220 is provided and controlled to actuate the pneumatic brake system 201b.

[0045] The pneumatic system 201 includes a valve 205 having an air outlet section 210 for discharging pressurized air 220. The valve 205 is adapted to control the flow of the air 220. The valve 205 may be mechanically and / or electronically controlled to be actuated to control the flow of the air 220. The valve 205 is adapted to discharge the air 220 through the air outlet section. The discharge of the air 220 may cause sound, such as noise.

[0046] The valve 205 comprises a damping member 100 mounted on and / or attached to an air outlet section 210. The damping member 100 is adapted to dampen acoustic emissions caused by pressurized air 220 by conducting the air 220 through the damping member 100.

[0047] Reference Figures 2 to 4 The damping member 100 is further described.

[0048] Figure 2 A perspective view showing details of a pneumatic valve 205 and a damping member 100 according to one aspect of the present disclosure. Figure 1 Schematically shown and referenced in Figure 1 Describe. Figure 1 To describe Figure 2 .

[0049] Figure 2The valve 205 is shown to include a housing 206. The housing 206 is adapted to accommodate a number of components of the valve 205, in particular fluid channels, a piston and an elastic element, such as a spring (not shown). Air 220 can be discharged from the valve 205. To discharge the air 220, the valve 205 includes an air outlet section 210. The air outlet section 210 includes an opening in the housing 206 through which the air 220 can be discharged from the valve 205 into the environment of the valve 205. The valve 205 is an example of a valve 205 for a lift shaft pressure distributor.

[0050] The damping member 100 (as indicated by the double arrow) is adapted to be attached and / or mounted to the valve 205, in particular the housing 206 and the air outlet section 210. The damping member 100 comprises a mounting portion 120 for fixing the damping member 100 directly to the valve body 206 of the valve 205. The mounting portion 120 comprises three circumferentially arranged clamping members (not shown). The mounting portion 120 is elastically deformable so as to clamp the clamping members to the valve body 206.

[0051] The damping member 100 includes a support structure 105. The support structure 105 is adapted to damp the acoustic emission and / or vibration caused by the outlet of the pressurized air 220 by conducting the air 220 through the support structure 105. The support structure 105 includes a plurality of structural elements 106, which are consolidated together to form the support structure 105. The plurality of structural elements 106 are adapted and arranged to form a repeating structure 105a and a layered structure 105b as the support structure 105. Thus, the structural elements 106 may be arranged in layers and, for example, periodically and repeatedly. The structural elements 106 may be equal to each other ( Figure 2 and Figure 3 ) and / or are different from each other ( Figure 4 ). The term "support structure" may refer to Figure 2 , Figure 3 and Figure 4 A plurality of repetitive features in the single-piece part or support structure 105 shown have the property of attenuating noise / vibration at the air outlet section. In particular, a plurality of repetitive features are distributed in the single-piece part in a manner equidistant from each other. These noises and / or vibrations are caused by the pressurized air leaving the air outlet section. It is also conceivable that the support structure can be a single-piece part consisting of a plurality of elements attached together and / or consolidated to form the support structure. The support structure is suitable for enabling the air flowing through the support structure to be deflected, distributed and / or diffused to the nearby atmosphere. This achieves damping, i.e., suppressing acoustic emissions such as noise, and / or suppressing vibrations.

[0052] The damping member 100 includes a plurality of holes 110 for damping acoustic emissions of air 220 conducted through the damping member 100. The holes 110 are arranged between the structural elements 106. That is, the cavities and / or gaps between the structural elements 106 form and provide the holes 110. The holes 110 are arranged and adapted to enable the air 220 to flow through the holes 110. The air 220 is deflected by the holes 110, and the velocity of the air 220 can be reduced by the holes 110.

[0053] The damping member 100 includes one or more functional portions 130 to prevent water intrusion, for generating a pressure gradient, for self-cleaning and / or for providing a mounting portion for a sensor (not shown). Figure 2 In the embodiment of the present invention, the functional portion 130 is formed as a cap, a cover and / or a plate located at the bottom surface of the substantially cylindrical support structure 105. The functional portion 130 protects the support structure 105 and / or its interior from water and / or dust. Specifically, the functional portion 130 prevents water from intruding. In addition, the functional portion 130 includes a plurality of openings to enable fluid communication between the hole 110 and the environment, thereby guiding the air 220 out of the support structure 105.

[0054] The damping member 100 is made of a polymer, in particular a thermoplastic and / or thermosetting polymer. In another embodiment (not shown), the damping member 100 is made of a metal and / or a composite material.

[0055] The damping member 100 is manufactured by an additive manufacturing process (see also Figure 5 ). The damping component 100 can be manufactured by using a so-called 3D printing process to shape and manufacture the necessary parts and elements of the damping component 100, in particular the support structure 105. The additive manufacturing process is based on a model 100' of the damping component 100 (see Figure 5 ), wherein flow, noise reduction properties, protection against environmental conditions and / or other undesirable influences required for a specific valve design can be taken into account. The shape and / or geometry of the damping member 100 can be individually adjusted for a dedicated design and available valve internal geometry. The damping member 100 can be a single piece integrated into the exhaust area of ​​the valve 205. The damping member 100 can be designed to form, for example, protection against water intrusion and also release air to escape freely from the confined volume. The support structure 105 reduces noise and enables high capabilities to prevent dirt and water intrusion, wide variability in shape, size formation and / or flow parameter control. Different filtration grades can provide different flow and / or filtration capabilities.

[0056] Figure 3 In the damping member 100 according to one aspect of the present disclosure Figure 3 (A) and Figure 3 Two stereograms are shown in (B). Figure 3The damping member 100 is as follows Figure 2 The damping member 100 is shown. Figure 1 and Figure 2 describe Figure 3 .

[0057] Figure 3 The substantially cylindrical shape of the stent structure 105 and the repeating structure 105a and the layered structure 105b along the cylindrical axis A are shown (see Figure 3 (B)).

[0058] Figure 4 According to one aspect of the present disclosure Figure 4 (A) and Figure 4 (B) A section of the damping member 100 . Figure 4 Each damping member 100 is as follows Figure 2 and Figure 3 An alternative to the damping member 100 shown. Figures 1 to 3 describe Figure 4 , which describes Figure 2 and Figure 3 The damping member 100 and Figure 4 The differences between the damping members 100 .

[0059] Figure 4 (A) shows a cross-sectional view of the support structure 105 (relative to the axis A, not indicated). The support structure 105 includes a plurality of functional guide members 115, which are suitable for guiding air 220 through the damping member 100. Among them, the functional guide member 115 is a structural element 106 arranged in the support structure 105. The functional guide member 115 is suitable for deflecting the main airflow 221 (schematically represented by a cross as flowing in the drawing plane). The functional guide member 115 for deflecting the main airflow 221 can be formed as a channel, which is suitable for guiding the air 220 to flow directly along the channel, for example, along the axis A and / or in a transverse direction (not shown). The functional guide member 115 is suitable for dividing the air 220 into a plurality of sub-flows 222 (as shown by the solid straight arrows). The sub-flows 222 are guided laterally from the main airflow 221 and are thereby distributed in the support structure 105. This enhances the damping performance.

[0060] The damping member 100 defines a flow direction F of the air 220 conducted through the damping member 100 (see Figure 1 The functional guide member 115 is adapted to reverse at least one component F1 of the flow direction F while the air 220 is conducted through the damping member 100 (see Figure 1 ), and / or the functional guiding component 115 includes a labyrinthine, winding and / or wavy shape 116.

[0061] like Figure 4(B) shows that the size of the hole 110 and the functional guide member 115 are different from each other. The damping member 100 drives and / or guides the air 220 to produce the desired noise damping characteristics, so that the desired flow path within the damping member 100 can be modeled. In addition, in addition to the ability of the damping member to damp the acoustic emission, the support structure 105 can also be used to damp and / or reduce the vibration caused by the air flow. In addition, the support structure 105 realizes reliable protection of the exhaust section 210 from environmental influences such as dust and / or fluids. This can be achieved by reducing the hole size in the flow direction.

[0062] Figure 5 A schematic diagram of a method 300 according to an embodiment of the present disclosure is shown. Figure 5 The method 300 is a method 300 for manufacturing the damping member 100. Figures 1 to 4 Such a damping member 100 is described. Figures 1 to 4 Describes Figure 5 .

[0063] Figure 5 The method 300 comprises the following steps: obtaining 310 a model 100 ′ of the damping member 100 .

[0064] The method 300 includes additive manufacturing 320 of a damping component 100 based on a model 100'. Therein, a plurality of damping components 100 can be produced by additive manufacturing 320 and based on the same model 100'. That is, the method 300 provides a series production of damping components 100. The number of damping components 100 produced can be adjusted according to current needs and can be rapidly expanded according to demand.

[0065] The model 100' depends on the geometry of the valve 205, the air outlet section 210 and / or the valve body 206. That is, the model 100' is constructed based on the geometry of the valve 205, the air outlet section 210 and / or the valve body 206. For example, the model 100' includes details related to the mounting portion 120, and the model 100' is suitable for being able to attach the damping member 100 to the valve body 206 near the air outlet section 210 through the mounting portion 120 so that the air 220 can flow through the damping member 100.

The computer-readable medium 400 may be and / or include any digital data storage device, such as a USB flash drive, a hard drive, a CD-ROM, an SD card and / or an SSD card.
